Java实现多线程的四种方式

java中实现多线程主要有四种方式：继承Thread类

一，继承Thread类，重写run方法

public class ThreadTest {
    //主线程
    public static void main(String[] args) {
        MyThread1 myThread1 = new MyThread1();
        MyThread2 myThread2 = new MyThread2();

        myThread1.start();
        myThread2.start();
        System.out.println("我是主线程");
    }
}

public class MyThread1 extends Thread{
    @Override
    public void run() {
        System.out.println("我是线程1");
    }
}

public class MyThread2 extends Thread{
    @Override
    public void run() {
        System.out.println("我是线程2");
    }
}
